strings on the bass strings side at the area between the bridge
and soundhole. Sometimes there is also a flat brace running pa-
rallel under the bridge. The AST should be placed so that the AST
is on the bass side of the brace running parallel to the strings and
that part of the active area of the AST, that has the lead to the
preamp, goes on the brace for the bridge. If the brace there is too
tall put the AST in front of the brace. Please read the instructions
carefully and adapt them to the installation.
To test fit the 1470 AST in a guitar with a bridge plate, take the
cardboard installation template from the tray in the box. Note!
There is a small 4.5 mm (.18”) round and a 4.5 mm (.18”) elon-
gated part that both need to be punched out to make their res-
pected guide holes. The 4.5 mm round guide hole is for the low
“E” bridge pin and the elongated guide hole to fit at the high “E”
bridge pin inside the guitar. Peel away the protective covers from
the two adhesive dots on the cardboard. Do not peel away the
actual AST mounting adhesive protective cover yet!
The placement of the AST is important for connection to the
preamp. For the A2 preamp, the AST’s lead goes away from the
high “E” side of the bridge area and towards the strap pin at the
butt end of the guitar
Now mount the AST to the top of the cardboard installation
template at the rectangle AST area inscribed on the cardboard.
Now put the assembly to the bridge pins, with the AST towards
the bridge plate and check the fit. All of the AST’s active area
must fit at the soundhole side of the bridge plate without hang-
ing over the edge of the bridge plate. Make sure that there is
enough space that the bridge pins or string ball-ends will not
touch the AST.

Next remove the strings, bridge pins and the saddle. If you
are using a UST, check that it fits into the slot easily and that the
saddle is sufficiently tight in the slot.
6.3
If the guitar has a strap button pin at the butt end of the gui-
tar, remove it and carefully enlarge the hole using 12 mm (.47”)
endpin reamer or 12 mm (.47”) wood drill bit. Smooth the edge of
the hole with a small file or a sinking drill bit.
If the guitar does not have a strap button pin and no hole, then a
12mm will have to be drilled with wood drill bit. We recommend
that a professional should do this. Put a piece of masking tape
where the hole will be drilled. This makes it easy to draw a point
where to start drilling. Use the punch to make a start hole. Use
a very small drill bit to make a starter hole and then finish by
using the 12mm (.47”) drill bit. Smooth the edge of the hole with
a small file or a sinking drill bit.
6.4 Drilling hole for UST
For UST check the inside of the guitar to find the position of the
braces. Drill a preferably 30 - 45 degrees angled, 2.3 mm (.09”)
or 3 mm (.12”) hole (depending on the model of your B-Band
UST) for the transducer into the one end of the saddle slot. Be
careful not to damage the braces!
In case you cannot make the hole angled, because of possible
damage to the braces, you can make it straight down.
It is very important to smooth the edge of the hole using a bit
of rolled sandpaper or a small file, to avoid pinching the UST as
the saddle lies on it. It is preferred, that the hole for the UST is
drilled at the low-E string side of the slot.
6.5 Installing battery holder
Before installing the battery holder it should be checked by in-
serting a 9-volt battery in and out of it to learn how it works.
Once this is checked, find a convenient place inside the guitar
where the battery holder can be reached and that there is good
access to the snap. Also check that it is in a place that the bat-
tery can be put in and out easily.
Recommended places are at the neck block or at the back of
the guitar.
Be sure that the entire adhesive surface will make full contact
with surface you are attaching it to. Clean the surface with a
moist cloth and let the moist dry completely. Remove the pro-
tective liners of the adhesive and install it. Press firmly for about
30 seconds to make it secure. It takes 72 hours for the adhesive
to achieve its final holding ability.
